No. This is a test that tests for cardio and pulmonary response to exercise. They use this on elite athletes and people like me who have chronic fatigue, shortness of breath (extreme) intolerance to exercise with exhausting every other lung and heart test out there. I also have intermittent bouts of hypoxia. I've had more tests than I can count over 3 years and finally had to give up tennis due to so much trouble with breathing. The last test that was run, just last week, was a cardiopulmonary test. Everything showed excellent and 10% better than women my age-- 63. But, one thing was not normal. I could not reach my peak heart rate during exercise. Blood pressure and heart rate were flat in response to exercise. So something called chronotopic incompetence is suspected. You will have to google it. I'm just now trying to understand it. One of the causes can be a congenital hole in the heart that didn't close up properly after birth. Cardiologist said if that's what it is, it is probably not large since I've made it this far. Apparently hole can be patched but I'm waiting to hear back to see what the plan is. If it's not that, then I don't have a clue. Hope I get to feel better and play tennis and exercise like I want again.
